Did you see this? An article at Wired Science explores the idea that urban sprawl, plus climate change, combined to manufacture last year’s devastating downtown tornado.

“The conditions that brought in the storm were the hammer,” analogized Purdue University climatologist Dev Niyogi, “but local features were the chisel. They pinpointed the severe weather.”

That tornado cut through town a year ago today, and as I type this it’s a mild rainy day inside the Perimeter, but just a few blocks from here houses still show their scars. If you know someone who was hurt personally when the sky came down to Atlanta that day, give them a call. Buy them a drink. Remember that strange and powerful day.
